Taxes owed not shown on site

I did my taxes for my current job, forgetting I'd be getting a W-2 from another job for a couple of months worked. I amended, was told I owe taxes, and now that I have my refund I can't find that info on the site. It looks like the answer is 'the IRS will take what you owe out of your refund before it's deposited,' but I just want to double-check and make sure I don't have to send out payments now. Thanks!
